View 1 RepliesI have a problem with farpoint spread sheet, that while loading the data into the spread sheet, the sheet refreshes each time a value is set.
I have large number of rows and columns so, the sheet take quite large time till loading.
any idea how to disable the refresh and enable it again after the data is completely loaded.
I'm using the Farpoint controls in VB.NET program. At times, i'm getting the error as follows:
************* Exception Text **************
System.Runtime.InteropServices.COMException (0x80040154): Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

Currow value=24 in this instance
Arsheet2b = ObjExcelB.Sheets(1).Range("A2:L" & curRow).value
<error>
System.InvalidCastException was unhandled
Message=Unable to cast object of type 'System.Object[,]' to type 'System.String[]'.

I can restrict the sheet from A1:A24 (contains 2010) and I get the same error.
at the moment I have a small application and need to take information from an object and display it into an excel file, using the Microsoft.office.interop class I've been able to write to the file, and it shows one by one the records being added, however about once every 3 times I try it, the spreadsheet stops filling somewhere between the 300th and 600th record, I have 6,000 in total and it's not breaking every time, I put a check after it finishes to see whether the last record is filled in but the code never reaches that point and I'm unsure of what's happening I also don't know how to debug the problem as it'd mean going through 6,000 loops to check for it stopping... which might not even happen?

I need to copy data using Vb.net if possible from one excel spreadworbook to another and place the data into the correct columns in the existing excel spreadsheet. The column titles of the spreadsheets match up, I have several templates I need to place data into and the order of the columns is different in each template so I need a way of searching for a column header in the template and then copying the data into that column.

Here is the code for one of my buttons that currently writes to the text document:

My app is a fairly simple and im sure with the right knowledge this would take 2 minutes.. but sadly iv been at it for hours. So my scenario here is a huge network with 20+ file servers all with data spread out across them it can take hours to find the folder required.
Hence this app.. so it consist of a input box, progress bar and a button, using FileSystemObject I plan to interrogate a directory to see if a folder exists (folder specified by user input) however it need to check multiple directories, in my old app I used a list box which wrote to a text file allowing the user to add additional directories then using if statements proceeded through the servers.. however they have added that much that my IF's have ran out really because i know it should have been a loop

I have looking for a tutorial or class that demonstrates more than a trivial example of saving a windows position on closing. The ones I have found don't seem to work on all systems because of:
1. Multiple monitors. (and resolution between those monitors)
2. Toolbar size and position (toolbar is only on the primary monitor, well sometimes)
3. Sometimes the programs dont open on the right monitor they were closed on.
Is there an extensive class or tutorial on all the stuff a programmer needs to get right to have a window size and position persisted between executions?

Input a range of numbers and sort them into 6 equal amounts and then having the program tell you which amount the number was put into?
I.e
Input:
1200, 2400, 600, 600, 300, 300, 1200, 1200
Sorted into:
Group A: 2400 = 2400
Group B: 1200 + 1200 = 2400
Group C: 600 + 600 + 300 + 300 + 1200 = 2400
I also have a function that returns ALL tiles on the map and they're X, Y position. How could I find out which one is closest to the position I specify? I can't figure out how to go about it. how to implement it with this. Heres a MADE UP example if what I'm trying to do:
Dim MyPosition as New Position()
MyPosition.X = 400
MyPosition.Y = 400
Dim tList as New List(Of Tile) = MyMap.GetTiles
Now, I can already do the stuff above, but what I need to make is something like this:
tList.GetTileClosestToPosition(MyPosition)
I have two forms: Main and Options.Main can be moved around the screen (like a normal window).When the user clicks a button, the Options form opens up and the Main form HIDES.How do I set the Options form to open in the exact place that the Main form was last on the screen (to give it the effect the MAIN form never went into hidding)I was thinking to set Option form's StartPosition to Main's current position, but I don't know the syntax for that or if it's even something you can do.

View 1 RepliesI have a string like this: mstring = "0123456789ABCDEF"
how can I get the vale at a given position, such as 12?
I know with PHP I can do this:
val = mstring{12}
and it will give me the twelfth value in the string, which would be "C"
I am getting the error there is no row at position 6 but there is data at position 6. May I know if there is any better way apart from this that will "see" the correct number of rows in the database and display out the correct rows in the database? So lets say you have one row auto - increment and one column containing the data. Currently now if i delete off the row no 6 and add back the row, the dataset cannot see this row anymore thus giving me the error, there is no row at position 6.
If i take off the auto - increment row and test this method out, i get the same error.
